Brightwell Aquatics Reef Code B Alkalinity Buffer for Reef Aquariums, 500 ml

Reef Code B alkalinity buffer is dosed as the carbonate half of a two-part method for calcium and carbonates, and it is intended for brackish, marine and reef aquariums. The bottle holds 500 ml, and 5 ml treats 25 gallons of water every other day, or as needed. Each millilitre of Reef Code B raises the alkalinity of 1 gallon of water by roughly 2.22 dKH, so the dose is tied to a measured alkalinity reading between 7 and 12 dKH.

Water type and alkalinity range this buffer suits

Reef Code B is for brackish, marine and reef aquariums, and the alkalinity it is dosed into should stay within 7 to 12 dKH. One bottle contains 500 ml of the buffer.

According to the manufacturer, ionic balance in natural seawater holds when Reef Code A and this product are dosed in equal amounts. A tank that is dosed with Reef Code A only, or in a ratio other than equal parts, falls outside that stated pairing.

A two-part buffer that follows seawater ratios

The buffer is the carbonate half of a two-part dosing method, and its dosing mirrors the ratios found in natural seawater. It maintains carbonates, bicarbonates, sulfates, borates and other anions, and it contains minor and trace minerals. The formula is a multi-component automatic buffer described as regulating pH, and it holds no phosphate, silicate or organic material.

• Dosing follows natural seawater ratios for the carbonate portion of the two-part method.
• Equal parts with Reef Code A are what maintain the ionic balance of natural seawater, as stated by the manufacturer.
• The buffer keeps up levels of bicarbonates, carbonates, borates, sulfates and other anions.
• Minor and trace minerals are included in the formula.
• No phosphate, silicate or organic material is in the bottle.

How much Reef Code B does a 25-gallon tank need?

What is the dose of Reef Code B?

For each 25 gallons of water, dose 5 ml of Reef Code B on alternate days, or as needed. One dose of 5 ml therefore treats 25 gallons of aquarium water.

How much does 1 ml raise alkalinity?

Each millilitre raises the alkalinity of 1 gallon of water by approximately 2.22 dKH. A 5 ml dose raises the alkalinity of 25 gallons by the same 2.22 dKH per gallon figure, so it is applied against a measurement rather than a fixed schedule.

What alkalinity should the tank be kept at?

Alkalinity should be maintained within the range of 7 to 12 dKH. The manufacturer directs that alkalinity is tested before dosing.

Which aquariums can Reef Code B be used in?

It is for use in brackish, marine and reef aquariums. Freshwater tanks are not among the water types listed.

How big is the bottle?

The bottle contains 500 ml of Reef Code B. The dose of 5 ml per 25 gallons is measured from that bottle.

Shaking, testing and the dosing routine

Shake the bottle well before use. Check alkalinity prior to dosing; then dose 5 ml of Reef Code B for every 25 gallons of water on alternate days or as needed, and hold the value between 7 and 12 dKH. Reef Code A is dosed in equal parts alongside it for the ionic balance of natural seawater.
